What was the event that touched off the first declaration of war in World War I?
Archduke Franz Ferdinand was in the line of succession to the Austro-Hungarian throne when he and his wife Sophie were assassinated on June 28, 1914, in Sarajevo. Members of a Serbian nationalist group carried out the assassination. The subsequent international crisis led to the outbreak of World War I. Show Following the assassination, the Austro-Hungarian Empire, supported by the German government, issued an ultimatum demanding among other things that Serbia cease all activities against Austria-Hungary. The Serbs, with Russian backing, refused the empire's demands. In response, Austria-Hungary declared war against Serbia on July 28. Russia entered the conflict on Serbia's side. Germany declared war first on Russia, then on France, who was militarily allied with Russia. The German offensive quickly violated Belgian neutrality, and the British declared war on August 4, 1914. Within six weeks of the assassination, Europe was at war. This timeline describes some key events related to World War I and its aftermath. August 26–30, 1914: The Battle of Tannenberg The Battle of Tannenberg fought between Russia and Germany, was one of the first battles of the war and the first major battle won by Germany on the Eastern Front. It resulted in the near complete destruction of the Russian Second Army. The victory at Tannenberg brought considerable prestige to Field Marshal Paul von Hindenburg and his staff-officer Erich Ludendorff, who would play prominent roles in Germany in the years to come. Spring 1915: Bryce Report—Committee on Alleged German Outrages After World War I, people realized that many of the stories had been greatly exaggerated and sometimes fabricated, which sparked scepticism about later atrocity stories. Consequently, as the first reports of Nazi atrocities began to emerge at the outbreak of World War II, many people discounted the information, based on experiences with the Belgian atrocities. April 22, 1915–May 25, 1915: Chlorine Gas Attack at the Second Battle of Ypres There were many artistic responses to the horrors of war. Wilfred Owen, one of the best-known poets of the war, later described a gas attack in his poem “Dulce et Decorum Est.” December 8, 1915: Publication of "In Flanders Fields" February 21–December 18, 1916: Battle of Verdun May 16, 1916: Sykes-Picot Agreement July–November 1916: Battle of the Somme Spring 1915–Autumn 1916: Armenia 1917: The Russian February Revolution April 6, 1917: United States Entry into World War I British Naval Intelligence intercepted a telegram from Germany’s Foreign Minister, Arthur Zimmermann, to Mexico, offering Mexico territory in the United States in exchange for Mexican help if America went to war against Germany. The decoded text of the telegram was turned over to the US Ambassador in London, and then sent to American President Woodrow Wilson. Using this information and Germany’s resumption of submarine warfare, Wilson went to Congress on April 2, requesting a declaration of war against Germany. Congress declared war several days later, on April 6, 1917. 1917: The Russian October Revolution November 2, 1917: Balfour Declaration January 8, 1918: Wilson’s Fourteen Points March 8, 1918: First Report of Spanish Flu November 11, 1918: Armistice December 1, 1918: Kingdom of Yugoslavia formed June 28, 1919: Treaty of Versailles April 25, 1919: Release of Abel Gance’s Film J’Accuse November 19, 1919/March 19, 1920: United States Senate Rejects Treaty of Versailles 1919: Founding of Weimar Republic August 27, 1928: Kellogg-Briand Pact 1929: Publication of All Quiet on the Western Front October 29, 1929: Stock Market Crash and the Great Depression While no country was spared from the Depression, Germany was especially hard-hit. The German economy had only just begun to recover from the economic effects of World War I, the Versailles reparation payments, and the terrible hyperinflation of 1923, which wiped out the savings of ordinary Germans. Germany’s economic woes, coupled with the weakness and instability of the Weimar Republic, made the German public more receptive to political messages such as Hitler’s, in which he promised to reject the Versailles Treaty and return to German greatness.
